Abstract
The invention concerns a method for the condensation of aromatic derivative(s) or a sulphinic derivative by a perhalogenated, advantageously perfluorinated, carbon atom. Said method is characterized in that it consists in subjecting said sulphinic derivative and said aromatic derivative to the action of a strong acid whereof the pKa is not more that 0. The invention is applicable to organic synthesis.
